The effect of tooth bleaching on the enamel surface and the tensile force to debond orthodontic brackets

摘要

With the growing awareness of aesthetic treatments, there is a great demand for solutions to problems such as food stains, fluorosis and the tetracycline staining of the teeth. The advent of vital bleaching has captured the imagination of the public and the dental profession by offering the option of a non-invasive and relatively simple procedure to produce a whiter, more attractive smile. Various whitening systems have been developed, and peroxide compounds at different concentrations are currently used to bleach tooth enamel. Tooth bleaching systems today have hydrogen peroxide as the active agent. Vital tooth bleaching can be performed at home and in-office; the latter is often used in combination with an activating agent such as heat orlight. The peroxide permeates the enamel and thus produces a lightening effect.
